       Thread Actions

       A thread action jumps to a specified bead on an article thread (see Section 8.3.2,
       “Articles”), in either the current document or a different one. Table 8.55 shows
       the action dictionary entries specific to this type of action.

                           TABLE 8.55 Additional entries specific to a thread action
KEY   TYPE                        VALUE

S     name                        (Required) The type of action that this dictionary describes; must be Thread
                                  for a thread action.

F     file specification          (Optional) The file containing the thread. If this entry is absent, the thread is
                                  in the current file.

D     dictionary, integer,        (Required) The destination thread, specified in one of the following forms:
      or text string
                                  • An indirect reference to a thread dictionary (see Section 8.3.2, “Articles”).
                                     In this case, the thread must be in the current file.
                                  • The index of the thread within the Threads array of its document’s catalog
                                     (see Section 3.6.1, “Document Catalog”). The first thread in the array has
                                     index 0.
                                  • The title of the thread as specified in its thread information dictionary (see
                                     Table 8.11 on page 596). If two or more threads have the same title, the one
                                     appearing first in the document catalog’s Threads array is used.
